-Before we begin, if you haven't already done so, you may wish to check that
-you have all the :doc:`prereqs` installed on the platform(s)
-on which you'll be developing blockchain applications and/or operating
-Hyperledger Fabric.

-Once you have the prerequisites installed, you are ready to download and
-install HyperLedger Fabric. While we work on developing real installers for the
-Fabric binaries, we provide a script that will :doc:`install` to your system.
-The script also will download the Docker images to your local registry.
+The Fabric application stack has five layers:

-After you have downloaded the Fabric Samples and Docker images to your local
-machine, you can get started working with Fabric with the
-:doc:`test_network` tutorial.

-Hyperledger Fabric smart contract (chaincode) APIs
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+* :doc:`Prerequisite software `: the base layer needed to run the software, for example, Docker.
+* :doc:`Fabric and Fabric samples `: the Fabric executables to run a Fabric network along with sample code.
+* :doc:`Contract APIs `: to develop smart contracts executed on a Fabric Network.
+* :doc:`Application APIs `: to develop your blockchain application.
+* The Application: your blockchain application will utilize the Application SDKs to call smart contracts running on a Fabric network.

-Hyperledger Fabric offers a number of APIs to support developing smart contracts (chaincode)
-in various programming languages. Smart contract APIs are available for Go, Node.js, and Java:
-
- * `Go contract-api `__.
- * `Node.js contract API `__ and `Node.js contract API documentation `__.
- * `Java contract API `__ and `Java contract API documentation `__.
-
-Hyperledger Fabric application SDKs
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Hyperledger Fabric offers a number of SDKs to support developing applications in various programming languages. SDKs are available for Node.js and Java:
-
- * `Node.js SDK `__ and `Node.js SDK documentation `__.
- * `Java SDK `__ and `Java SDK documentation `__.
-
- Prerequisites for developing with the SDKs can be found in the Node.js SDK `README `__ and Java SDK `README `__.
-
-In addition, there are two more application SDKs that have not yet been officially released
-(for Python and Go), but they are still available for downloading and testing:
-
- * `Python SDK `__.
- * `Go SDK `__.
-
-Currently, Node.js, Java and Go support the new application programming model delivered in Hyperledger Fabric v1.4.
-
-Hyperledger Fabric CA
-^^^^^^^^^^^^^^^^^^^^^
-
-Hyperledger Fabric provides an optional
-`certificate authority service `_
-that you may choose to use to generate the certificates and key material
-to configure and manage identity in your blockchain network. However, any CA
-that can generate ECDSA certificates may be used.
